SPECIFICATION forming part of Letters Patent No. 294,702, dated March 4, 1884;

Application filed October 6, 1883. (No model.) I

To (all whom it 72mg concern.-

Be it known that I, WVARREN H. TAYLOR, a citizen of the United States, residing in Stamford, in the county of Fairlield and State of Connecticut, have invented. certain new and useful Improvements in Locks, of which the lock particularly useful for a desk-lock, but

7 represented in the locked'position.

of course applicable wherever it is desirable to have a spring-lock that will always stand in the locked position when the key is removed, and is also always deadlocked in that position, so that it cannot be unlocked, eX- cept by the use of the proper key. In 0011- nection with such a look I provide a spring strike or catch, in order that a desk or the like may be closed and spring-locked, and at the same time dead-locked without the use of a key. I

In the accompanying drawings, Figure 1 is a front elevation ofa lock and a spring-strike made in accordance with my invention, and Fig. 2 is a front elevation of the same, represented in the unlocked position, as when the key is in-- serted and turned. Fig. 3 is a rear elevation of the same, showing the parts in the relation they occupy during the operation of automatically locking by closing a desk or the like without the use of the key. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5 is a section on the line 5 5 of Fig. 1; and Fig. 6 is an elevation of a platekey bitted alike on both sides, so that it may be inserted either side up to operate the lock.

The tumbler mechanism A and the case B of the lock are of ordinary construction, and need not be particularly described. The lockbolt 0, of hooked. or angular form, projects through the face-plate of the lock, and is connected with or is a part of a sliding plate, D, provided with an elongated opening in which is formed a rack, E, with which gears a pinby means of a talon or the like-may be employed.

It is not necessary to have a plate-key bitted alike 011 both sides, but that is preferable for convenience. lVhen the key is inserted and turned, it first spreads the tumblers so as to bring them in coincidence, as shown in Fig. 2, and then slides the plate D and lock-bolt to one side, as also represented in Fig. 2, into the unlocked position. As the key is turned back in order to get it outof thelock, it nee essarily throws the bolt into the locked position, and permits the tumblers to return by their springs also to the locked position, as shown in Fig. 1.

I provide a springstrike, H, in. connection with a face or jam plate, I, of hooked or angular shape, corresponding, substantially,

with the lock-bolt, and pivoted at K-and provided with a spring, L, and a stop, M. The upper corner of the lock-bolt next the springstrike and the lower corner of the spring strike next the lock-bolt are rounded or beveled, so that when it is desired to close the desk the rounded part of the lock-bolt -will impinge against the rounded part of the spring s'trike and bear the latter to one side, as shown in Fig. 3, until the bolt passes the end of the strike,when it will spring into the locked position, as shown in Fig. 1.

Various formal modifications, both of the lock, the bolt, and the strike and its conneeted parts, may be made without departing from the substance of my invention.

It will thus be obserted that I provide a locking mechanism which is very secure and very convenient. It cannot be unlocked without the use of the key, yet will lock automatically by merely closing a desk or the like, and always stands dead-locked when the key is out. The strike is so concealed that it cannot be reached by any instrument, and the lock-bolt cannot be pushed into the unlocked position by the insertion of any instrument. This is specially convenient and secure for desks, because the user will ordinarily unlock his desk, open it, remove the key, and when he shuts the lid down,which he may wish to do hurriedly, the desk will be thus locked by In testimony whereof I have hereunto subro a deadlock.
